LOOSE-SHEET BINDER.

Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed May 21, 1918. Serial No. 235,875.

To all whom it may concern:

Be it known that I, CHARLES- O. CARPEN- TER, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Loose-Sheet Binders, of which the following specification is a full disclosure.

My invention relates to a loose sheet binder and particularly to a type known as a ledger binder.

An object of the invention is to provide a simple mechanism for holding loose sheets to meet the prevailing requirement for machine posting.

Another object of the invention is to provide an expansible binder frame composed of separable sections, each section carrying sheet holding posts and a hinged cover and serving as a tray, the posts holding the sheets in relative alinement and registry.

The sheets may be transferred, inposting,

from one section to the other, the posts as guides enabling the sheets to be properly positioned upon the trays or binder sections for binding when the binder sections are brought together and united.

Another object of the invention is to provide an expansible binder frame with a series of sheet-holding posts consisting of sectional posts rigidly fixed within the binder frame and engaged into notches in the binding end of the sheets, alining and registering the sheets with one another, and a compressible removable post to engage through an aperture in the binding edge of the sheets for securely holding and confining the sheets within the binder frame.

Another object of the invention is to provide a binder frame composed of separable sections, each carrying sheet-holding posts, the posts of asection engaging with the opposite section for locking the sections together.

Other objects and features of the invention, some relating to structural details will more fully appear from the detailed de scription of the accompanymg drawings, illustrating a preferred embodiment of the invention, and made a part hereof, and in the drawings like characters of reference denote corresponding parts. throughout the sev eral views, of which Figure 1 is an elevation of a loose sheet binder containin my improvements.

Fig. 2 is a section on line 2-2, Fig. 1.

Fig. 3 is a plan View of one side of the binder frames, illustrating the locking devices mounted upon one of the frame sections engaged with the ends of a series of sheet engaging posts secured to and projecting from an opposite section for locking the binder sections together in their compressed position.

Fig. 4 is a section on line l i, Fig. 2.

Fig.- 5 is a plan view of the notched and apertured end of a sheet used in the binder.

Referring to the drawings, 1 indicates an extensible back frame of the binder between which the sheets are confined and to which the opposite covers 2 and 8 are hingedly connected. The binder frame is composed of two telescopically engaged and separable sections, the sections formed of angle plates arranged to provide opposite pin-carrying side walls 4, 4 and adjacent back walls 5, 5, telescopically united for moving the side Walls toward or apart from each other, to expand the frame, to insert or remove the sheets, or change the sheet-holding capacity of the frame. One of the angle plates has its back wall provided with inwardly extended tangs or hook extensions 6, 6, respectively engaging over the ends of the back wall of the opposite binder frame section for a telescopic engagement of the two frame sections or members, slidably uniting the same and also to make the parts separable. For the given size or hinder shown, each side wall is provided witha pair of sheet engaging pins or posts 7, 7*,with the pins of both sections arranged as a series at equispaced distances apart and in relative alternate arrangement for the purpose to be presently described.

Each pin has one of its ends rigidly fixed to the side Wall 4 or 4 of its respective binder frame section and is alined to register and engage its opposite end through an aperture in the side wall of the opposite frame section when the frame is compressed or in a closed position. Each of the pins or posts 7 1s of sectlonal form, with its sections detachably united and of the same or different lengths for changing the total length of the posts, to increase or decrease the capacity of the binder. As shown in Fig. 2, each post 7 is comprised of three sections, one section 8 may be termed a base post section having a threaded stud at one end engaging through an aperture in a side Wall of the binder frame and clamped there ill) - frame section of the side Wall.

to by a nut 9 rigidly securing the post with l in the binder frame.

The opposite end of the base post section 8 has a threaded bore to receive the threaded stud of a second or intermediate post section 10. This second post section 10 has its opposite end provided with a threaded bore to receive the threaded stud of a top post section 11, having its opposite or free end rounded and engaging into an annular flange, forming an opening or aperture in the opposite The sections are eachprovided with a cross-bore 12 therethrough, for receiving a wrench to tighten or loosen the sections. The sectional post is of commercial construction and no novelty individually is claimed therefor herein and for an invariable capacity binder the posts may be of a solid definite length,

7 The'side wall i upon its outer face has a latch-plate l3 slidably mounted thereon, brought together without readjusting the sheets. The sheets in posting; may be oil- The plate 13 has two elongated slots 1% cut therethrough, through which respectively the headed pins 15 fixed to the side wall 4% engage tor slidably mounting the latch plate in position. The latch plate has a second set 01 slots l6, 16, each formed to provide a key 17 at one end of the slot, adapted to engage into an annular groove in a post projecting through a post aperture in the wall 4 for locking" the binder frame section in a compressed or closed position. As shown. the annular flange forming the post receiving aperture in said side wall is cut away ifor clearance for the key portion 17 of the latch-plate. The inner end of the latch-plate 13 is fian 'ed upwardly and apertured to receive the guide pin 18, fined to and projecting from the bracket plate 19, secured to the side wall i The pin 18 carries a spring 910 interposed between the flanges or" the bracket-plate l9 and latchplate 13 for urging the latch-plate into engagement with the posts 7.

The outer end of the latch-plate is flanged inwardly to provide a head 22 to be engaged by the operator. tor actuating the latch-plate to reiease its engagement,

to expand the binder frame or separate its frame sections from one another. The latchplate will snap into engagement with its cooperating posts as soon as brought into a registering position when frame sections together.

The posts 7 may be referred toes permanent posts, rigidly secured to opposite binder sections to engage into uniformly spaced notches 23 of the sheets the notches being open. at the binding edge of the sheet. The sheets are also provided with an aperture to receive a compressible post, as a removable post, engaged between the binder sections, as a means for securely binding; the sheets within the binder frame. This removable post comprises two telescopic post pressing the sections 26, 27, section 26 being tubular with one end closed and studded to engage into an aperture in the ironic section 4:. The opposite end telescopically receives the post section 27, which is provided with a headed end for confining it within the tubular section 26, and a. spring 28 within the tubular section 26 engages the head of the post section 27 to force the same outwardly.

This binder is especially adapted for holding the sheets for machine posting, which enables the two frame sections to be oppositely supported upon a suitable rack, and the binder sections thus qualify as sheet-holding trays, each having rigid posts for holding the sheets against lateral displacement upon the binder sections or trays. The sheets in posting are transferred from one frame section to the other and the two frame sections with their sheets can be set, if desired, as the ends of the frame section are open for such purpose, and in using; sheets having a series of equob -spaced apertures 2i, an aperture of each sheet i then be brought into registry with ll movable post and thereby locked in the binder nine 111 its ofi set position.

The binder is susceptible to the various n'evailing methods of use, which need not be explicitly mentioned herein.

has been found desirable to support the free ends of the posts upon the l l ls of the respective trains s ctions. wi ch they are secured, or, at let it, employ some of the posts of the series to prevent sa meet the posts, thereby destroying the alinenidiit and registry the aperture in the opposing binder section into which 1'] when the binder frame is or ciosed.
